HTC wildfire with PC

I would like to know one thing. Is it possible to make phone call like this if i will connect my Htc wildfire with cable to computer and Bluetooth headset with the phone and use some kind of application to dial number directly from my pc and make calls without picking up the htc. Use my bluetooth headset to speak. Is this kind of application available or do you have any idea how could i do this thing? Its needed for our telemarketing person. I guess lots of companys would be interested in it.
